阅读本文之前请先了解ThinkSDK的文档
本文基于ThinkSDK,为其补充微信登录demo
增加ThinkSDK的微信第三方登录
1、配置文件增加相应参数
- //支付宝登录
- 'THINK_SDK_WEIXIN' => array(
- 'APP_KEY' => '', //应用注册成功后分配的 APP ID
- 'APP_SECRET' => '', //应用注册成功后分配的KEY
- 'CALLBACK' => URL_CALLBACK . 'weixin',
- ),
2、WeixinSDK代码
- <?php
- class WeixinSDK extends ThinkOauth
- {
- /**
- * 获取requestCode的api接口
- * @var string
- */
- protected $GetRequestCodeURL = 'https://open.weixin.qq.com/connect/qrconnect';
- /**
- * 获取access_token的api接口
- * @var string
- */
- protected $GetAccessTokenURL = 'https://api.weixin.qq.com/sns/oauth2/access_token';
- /**
- * API根路径
- * @var string
- */
- protected $ApiBase = 'https://api.weixin.qq.com/';
- public function getRequestCodeURL()
- {
- $this->config();
- $params = array(
- 'appid' => $this->AppKey,
- 'redirect_uri'=>$this->Callback,
- 'response_type'=>'code',
- 'scope'=>'snsapi_login'
- );
- return $this->GetRequestCodeURL . '?' . http_build_query($params);
- }
- /**
- * 获取access_token
- * @param string $code 上一步请求到的code
- */
- public function getAccessToken($code, $extend = null){
- $this->config();
- $params = array(
- 'appid' => $this->AppKey,
- 'secret' => $this->AppSecret,
- 'grant_type' => $this->GrantType,
- 'code' => $code,
- );
- $data = $this->http($this->GetAccessTokenURL, $params, 'POST');
- $this->Token = $this->parseToken($data, $extend);
- return $this->Token;
- }
- /**
- * 组装接口调用参数 并调用接口
- * @param string $api 微博API
- * @param string $param 调用API的额外参数
- * @param string $method HTTP请求方法 默认为GET
- * @return json
- */
- public function call($api, $param = '', $method = 'GET', $multi = false){
- /* 腾讯微博调用公共参数 */
- $params = array(
- 'access_token' => $this->Token['access_token'],
- 'openid' => $this->openid(),
- );
- $vars = $this->param($params, $param);
- $data = $this->http($this->url($api), $vars, $method, array(), $multi);
- return json_decode($data, true);
- }
- /**
- * 解析access_token方法请求后的返回值
- */
- protected function parseToken($result, $extend)
- {
- $data = json_decode($result,true);
- //parse_str($result, $data);
- if($data['access_token'] && $data['expires_in']){
- $this->Token = $data;
- $data['openid'] = $this->openid();
- return $data;
- } else
- throw new Exception("获取微信 ACCESS_TOKEN 出错:{$result}");
- }
- /**
- * 获取当前授权应用的openid
- */
- public function openid()
- {
- $data = $this->Token;
- if(!empty($data['openid']))
- return $data['openid'];
- else
- exit('没有获取到微信用户ID!');
- }
- }
- ?>
3、获取信息的接口
- //登录成功,微信用户信息
- public function weixin($token){
- $weixin = ThinkOauth::getInstance('weixin', $token);
- $data = $weixin->call('sns/userinfo');
- if($data['ret'] == 0){
- $userInfo['type'] = 'WEIXIN';
- $userInfo['name'] = $data['nickname'];
- $userInfo['nick'] = $data['nickname'];
- $userInfo['head'] = $data['headimgurl'];
- return $userInfo;
- } else {
- throw_exception("获取微信用户信息失败:{$data['errmsg']}");
- }
- }
